Description

Bone conduction receiver

The present invention relates to a bone conduction receptacle, and more particularly to a bone conduction receptacle using a bone conduction horn that can be used unhindered, whether for a normal hearing or a hearing impaired.

In the case of using a bone conduction horn, the best delivery site for the bone conduction output can be considered as the mastoid at the posterior side of the auricle, and the bone conduction horn is configured to crimp its vibration surface to the mastoid. The department is the best. In addition, in the bone conduction receptacle of the bone conduction horn into the ear strap of the ear-hook earphone or the eyeglass, the bone conduction horn is generally not easy to see from the front because it is required to be placed in a conspicuous manner as far as possible. The posterior side of the auricle is placed in a manner that is crimped to the mastoid.

In addition, in the case where a normal hearing person uses a bone conduction horn, the method of transmitting the bone conduction most efficiently is to arrange the bone conduction horn around the ear hole (especially on the tragus). This is because, in the case where the normal hearing person uses the bone conduction horn disposed at the position where the posterior side of the auricle is crimped to the mastoid portion, the tympanic membrane information is prioritized and transmitted at a sufficient volume. Bone conduction output can become difficult.

However, in consideration of the use of a normal hearing person, the bone conduction horn of the bone conduction receiver is disposed on the periphery of the ear hole (especially on the tragus), because it may become a violation of the bone conduction horn as far as possible. The requirement to see from the outside is usually given priority to this requirement, and is configured to arrange the bone conduction horn on the rear side of the auricle. The result is In the case of a normal hearing person using a bone conduction acceptor, it will fall into a dilemma where it is difficult to transmit information at a sufficient volume.

As described above, the bone conduction horn of the bone conduction receiver is generally disposed on the posterior side of the auricle because it is not required to be placed too conspicuously. However, in the case of a normal hearing person using the bone conduction receiver of this configuration, Underneath, there will be problems with the difficulty of transmitting information at a sufficient volume. Accordingly, it is an object of the present invention to provide a bone conduction receiver which is configured to dispose a bone conduction horn on the rear side of the auricle so as not to be easily seen from the outside, and can be sufficiently used even in the case of a normal hearing person. The volume delivers sound, even if it is used by the hearing impaired.

In order to solve the above problems, a first aspect of the invention provides a bone conduction receiver characterized in that a bone conduction horn is disposed at a rear side of the auricle at the time of attachment, and at a position thereof, the vibration surface of the bone conduction horn Directly or indirectly, it abuts against the back of the auricle, and the auricle functions as a vibrating piece.

In a preferred embodiment, the vibrating surface of the bone conduction horn is configured to face the rear of the auricle and move back and forth. In this case, the vibrating surface of the bone conduction horn is provided such that the entire bone conduction horn is movably disposed in the front-rear direction, and is opposed to the rear of the auricle and can be moved back and forth.

In one embodiment, the bone conduction horn is along the temple of the glasses or The ear strap type headband is set to move back and forth. In this case, the bone conduction horn can be moved back and forth by being fixed to a sliding member that is fixed to the temple or the ear-hook headband along the eyeglasses so as to be movable back and forth.

In addition, in an embodiment, the bone conduction horn is configured to The above-mentioned bone conduction horn is biased toward the front side, and the elastic force of the elastic material supported on the one hand is opposite to the auricle and can be moved back and forth. The elastic material is, for example, disposed in a horn holding portion in which a foot cover of an end portion of the temple of the eyeglass is enlarged. In addition, the elastic material is formed integrally with the bone conduction horn, and is disposed on the sliding member disposed along the temple or the ear strap of the glasses in such a manner as to be movable back and forth. .

In still another embodiment, the bone conduction horn is configured to be horizontal The support is rotatably supported.

The bone conduction receiver of the present invention is constructed as described above, and on the one hand, the bone conduction horn is disposed on the rear side of the auricle which is not easily visible from the outside, and the vibration surface of the bone is radiated on the one hand. Directly or indirectly abuts the posterior side of the auricle, so that its vibration output is directly transmitted to the auricle and the auricle itself acts as a vibrating piece to generate sound pressure. Further, since the sound pressure reaches the tympanic membrane through the ear hole, it can be heard at a sufficient volume even when the normal hearing person uses it. In addition, in the case of a hearing-impaired person, since the vibration output is transmitted from the auricle and its periphery, it is sufficiently smaller than the direct output of the skull vibration.

In addition, since the bone conduction horn is disposed along the temple or the ear-hook headband of the glasses, and is supported to be rotatable in the horizontal direction, it has a separable The effect of use, that is, when the normal hearing person uses it, the vibrating surface is rotated in the direction of abutting the auricle so that the auricle is vibrated, and the hearing aid is used or the auricle is suppressed. In the case of a leak caused by vibration, the vibrating surface is rotated toward the mastoid side for use.

Figure 7 is a cross-sectional view showing the state of the auricle contact of the bone conduction horn in the bone conduction receiver of the present invention.

Embodiments of the present invention will be described with reference to the drawings. The bone conduction receiver of the present invention is characterized in that, when installed, the bone conduction horn 1 is located on the rear side of the auricle 20, and is disposed at this position such that at least a part of the vibration surface 3 of the bone conduction horn 1 is directly or indirectly Abuts behind the auricle 20 . Moreover, the basic structure of the bone conduction horn 1 itself is not particularly different from the general bone conduction horn.

The bone conduction receiver is usually configured in the form of a glasses type or an ear-hook type earphone. In the first embodiment shown in FIG. 1, the bone conduction receiver is configured as a glasses type. In this case, the bone conduction horn 1 is attached to the middle portion of one or both of the temples 11 of the glasses. The mounting position is such that the bone conduction horn 1 comes to the rear side of the auricle 20 when installed, and at least a portion of the vibration surface 3 abuts behind the auricle 20.

Needless to say, of course, the size around the head varies from person to person, in order to In use, at least a portion of the vibrating surface 3 of the bone conduction horn 1 is surely abutted against the posterior surface of the auricle 20, which is preferably configured such that the bone conduction horn 1 can move back and forth along the temple 11.

The means for moving back and forth along the temple 11 can be any means, for example For example, as shown in FIGS. 1 and 2, a simpler method is to arrange a sliding member 4 slidably inserted into the temple 11 on the upper surface of the outer casing 2. In the case of this configuration, the bone conduction horn 1 can be slidably moved to a desired position by pinching the temple 11 and pushing and pulling the sliding member 4. Further, in the case of this configuration, it is necessary to impart a certain degree of sliding resistance to the sliding member 4 in such a manner that the temples 11 are tightly fitted so that the bone conduction horn 1 does not excessively move.

Moreover, in a preferred embodiment, the bone conduction horn 1 is supported as a phase The sliding member 4 can be rotated in the horizontal direction (refer to FIG. 2). In order to design such a configuration, for example, the outer casing 2 may be suspended from a suspension shaft 5 rotatably provided on the bottom surface of the sliding member 4, or the outer casing 2 may be rotatably suspended to be fixed to the bottom surface of the sliding member 4. Suspension shaft 5.

In the second embodiment shown in Fig. 3, the bone conduction receiver is configured as a head. In the case of a headphone type, in this case, the bone conduction horn 1 is provided on one side or both sides of the headband 12. This mounting position is similar to the case of the above-described eyeglass type, and the bone conduction horn 1 is brought to the rear side of the auricle 20 at the time of installation, and at least a part of the vibration surface 3 abuts against the rear of the auricle 20.

The second embodiment is also a case for bone conduction in use. At least a part of the vibrating surface 3 of the horn 1 is surely abutted against the posterior surface of the auricle 20 The guide horn 1 is movable forward and backward along the headband 12. Further, it is preferable that the bone conduction horn 1 is rotatable in the horizontal direction with respect to the slide member 4. The composition for this purpose is compared with the case of the above-mentioned eyeglass type.

The third embodiment shown in FIGS. 4 to 6 and the first embodiment described above Similarly, the bone conduction receiver is configured as a spectacle type, but the bone conduction horn 1 is not provided in the intermediate portion of the temple 11 as in the first embodiment, but is incorporated in the temple 11 The end of the horn holder 13 is formed by the end foot sleeve being enlarged.

In this case, the vibrating surface 3 of the bone conduction horn 1 is directed by one side The elastic force of the elastic material 7 supporting the bone conduction horn 1 while supporting the bone conduction can be moved back and forth with the abutment of the auricle 20. The elastic material 7 is an elastic resin block or a spring, and is disposed in the horn holding portion 13.

The bone conduction horn 1 of the configuration example shown in FIG. 4, FIG. 5 and FIG. 6(A) is It is fixed to one end of the slide shaft 6, which is slidably supported in the support cylinder 14 formed inwardly at the front end surface of the horn holding portion 13. The other end of the slide shaft 6 faces the inside of the horn holding portion 13, and is fixed to the elastic material 7. In this case, the bone conduction horn 1 is always in a state in which potential energy is applied forward by the elastic force of the elastic material 7, and as long as no load is applied, it is in a state of being most prominent in the front. A flange-shaped braking portion 6a is usually formed at the inner end portion of the sliding shaft 6, and the braking portion 6a is locked to the inner end portion of the support cylinder 14 to restrict the front moving end of the sliding shaft 6.

In addition, the bone conduction horn 1 of the configuration example shown in FIG. 6(B) is attached to the horn. The holding portion 13 is fixedly disposed on the elastic material 7, and the contact unit 8 is fixed to the vibrating surface 3 thereof. The contact unit 8 is slidably supported on the support cylinder 14 and has a front end portion that protrudes from the horn holding portion 13, and generally has a contact piece 8b whose front surface is curved. The inner end portion of the contact unit 8 is also formed with a braking portion 8a for the purpose similar to the above.

In all of these cases, the vibration surface 3 of the bone conduction horn 1 (in the case of Fig. 6(A)) Alternatively, the contact piece 8b (in the case of FIG. 6(B)) functions to be pressed in accordance with the size of the head of the user when abutting against the back surface of the auricle 20, but by an elastic material. The elastic force of 7 is stabilized at a certain position, and a suitable crimping force is supplied to the rear surface of the auricle 20.

Furthermore, due to the situation of the embodiment, the vibrating surface 3 faces the front and the rear. The moving stroke depends on the degree of expansion and contraction of the elastic material 7, and is therefore in a small range. Thereby, in order to increase the movement stroke of the bone conduction horn 1, it is also possible to use a method in which the bone conduction horn 1 as a whole can be moved. Therefore, for example, it is conceivable that the structure in which the bone conduction horn 1 is held by the elastic material 7 is made small and independent like the horn holding portion 13, and is fixed to the sliding member 4.

In any of the above embodiments, the bone conduction horn 1 is located at the time of installation. The posterior side of the auricle 20 is set to the vibrating surface 3 directly or via the contact unit 8 fixed to the vibrating surface 3, and is abutted against the rear surface of the auricle 20 with an appropriate pressure contact force (refer to FIG. 7). This setting operation is performed by each user to adjust the movement of the bone conduction horn 1 according to the size of the head of the user, or automatically by the action of the elastic material 7.

In this manner, when the vibration surface 3 of the bone conduction horn 1 is directly or indirectly abutted against the auricle 20 and the vibration output is transmitted, the auricle 20 itself becomes a vibration piece to generate a sound pressure. Moreover, this sound pressure will of course reach the tympanic membrane through the ear hole 21, so that if it is a normal hearing person, it can be heard at a sufficient volume. That is, similar to the case where the bone conduction horn 1 is brought into contact with the periphery of the tragus, both of the sound pressure and the vibration output can be transmitted. Further, in the case of use by a hearing impaired person, since the vibration output is transmitted from the auricle 20 and its periphery, the output of the skull vibration is slightly smaller than that of the skull, but it can be sufficiently heard.

In the case where the bone conduction horn 1 can be moved back and forth and rotatably, it can be used separately according to the situation, that is, when the normal hearing person uses it, the auricle 20 is vibrated. In a manner, the bone conduction horn 1 is moved toward the position and direction of the posterior surface of the auricle 20 toward the vibrating surface 3, and the bone is used in the case of the hearing impaired or to suppress the leakage due to the vibration of the auricle 20. The conductive horn 1 is moved toward the mastoid side for use.

The preferred embodiments of the present invention have been described in some embodiments, and it is obvious that various embodiments can be constructed in a wide range without departing from the spirit and scope of the invention. Therefore, the invention is not to be limited by the scope of the appended claims.
